This article illustrates the utilization of multi-state generating unit models in unit commitment risk analysis of a wind-integrated electric power system. The IEEE reliability test system is used as the study system and has been augmented using actual generating unit data from the Canadian Electricity Association database to include multi-state models for the larger units. The effects on the unit commitment risk and on the peak load-carrying capability of the IEEE reliability test system due to adding wind-generating capacity are illustrated using a series of studies dealing with scheduled operating capacity levels, generating unit derated state models, and wind conditions.

Keywords: derated state models; increase in peak load-carrying capability; peak load-carrying capability; unit commitment risk; wind power distributions
